HAIR-UNDULATING 'IONGS.

Application filed December 8, 1926, Serial No. 153,434,.and in NorwayDecember 12, 1925.

My invention relates to hair undulating tongs of that kind in which thehair is grasped between gutter-like members, of which one has a convexouter surface and the other a concave inner surface. My improvements inhair undulating tongs of this type relates partly to means for holdingthe hair only in the middle portion of the said gutter-like members sothat the adjacent hair portions hang freely between the side portions ofthe said two gutters, and partly to a needle arrangement for moving thefreely hanging hair portions in the longitudinal direction of thegutters all as described hereinafter.

The invention is illustrated diagrama-tical-- ly and by way of exampleon the accompanying drawing on which Figure 1 is a perspectiveillustration of hair undulating tongs designed according to thisinvention; Figure 2 is a side View of a modification; Figure is alongitudinal section through the parts shown in the upper half of therighthand portion of Fig. 2 this Fig. (3) being drawn to an enlargedscale and turned by an angle of ninety degrees relativelyto' saidportion of Fig. 2; and Figures 4 and 5 are cross-sections through theundulating members of the tongs, these members being shown in twopositions, all as fully described hereinafter.

Referring to 1, 1 and 3 denote two gutter-like undulating members, and 2and 4 denote grips firmly connected with said members so as to formtongs, as shown. The member or gutter 3 fits into the member or gutter1, but the radius of curvature of its convex surface is alittle shorterthan the ra dius of curvature of the concave surface of the gutter 1.The difference is, however, only slight. At any rate, the respectivesurfaces contact with each other intimately only at their middle lines,whereas there is no rims of the gutters extend somewhat outwardly likenarrow flanges; the upper face of the rims or flanges of the gutter 1 isconvex in cross-section, as shown at 5, and the lower face of the rims,or flanges 8 of the gutter 3 is concave in cross section, as shown at6, and slots 7 provided in said convex rimsof flanges can receiveneedles projecting downwardly from the legs of a U- shaped bow 9 locatedin guide ways extending along in the rims or flanges 8. The bow 9 can beshifted in said guide-ways. The needles 10 extend downwardly throughslots The communicating with the said guide-ways and I terminating atthe grooves 6 so that the need.es can be moved along in these grooves.

D If the tongs are to be used, the hair is held fast on the bottom ofthe gutter 1 between this and the adjacent portion of the lower surfaceof the gutter 3 so that it passes freely through between the flanges ofthe two gutters and. can be shifted therebetween in their longitudinaldirection. i

The tongs may be heated electrically by means of heating bodies enclosedin suitable parts of the tongs.

In the modification shown in Fig. 2, the gutters 11 and 12 areaflixed tothe arms '14 and 15 of double-armed levers jointed to one another by apivot 13 and the other arms 26 and 17 of which form the grips of theongs.

Thev gutter 11 carries a slide 18 which can be shifted along said gutterand is provided with two rows of downwardly extending pins 19, as shownin Figs. 4- and 5. The bottom of the gutter 11 is slotted and containsin its slot a ledge 20 which can be moved out wardlypand inwardly,aswill appear from a comparison of the Figs. 1 and 5. The means for thusmoving the ledge 20 may be of any desired kind. In the example shown, acam 21 18 secured to a shaft 22 supported in cross walls 23 of thegutter, and cranked at its outer end 24 where a grip 25.is attached tothis end whereby the shaft 22 and the cam 21 can be turned/ The shaft 22passes also through sleeves/28 connected firmly with the slide 18,andspaclug tubes 27 are inserted between these sleeves and the cam 21 sothat when the shaft 22 is shifted axially in its bearings 23 the cam 21is shifted in this direction, as is also the slide 18 with its needles19. In other words, the shaft 22 serves not only for. actuating the cam21., but also for actuating the slide 18. The axial movement of theshaft 22 is limited by spacing tubes 28 located upon said shaft betweenthe sleeves: 26 and the walls 23 which latter serve, therefore, also asabutments for said spacing tubes (28).

The vertically movable vented from leaving the bottom slot of the gutter11 by projections 29 provided at its ends, and preventing the ledge alsofrom being drawn out unintentionally.

When the tongs is to be used. for undulating hair, this latter is placedin the usual ledge 20 is pre- I i turned too far, it is provided withprojec tion contacting with the ledge when this latter has arrived inits lowermost position (Fig. 5). Thehair is therefore held fast betweenthe middle portion of the gutter 12 and ledge 20. Now the slide 18shifted in the one or the other direction according to its position uponthe gutter ll, whereby the 7 free hair portions projecting forth betweenthe rims of the utters arc shifted by the needles '19 "nto the properposition for the undulation procedure. Then the grip 25 is turned backinto its former position Whereby the ledge 20, is permitted to re-enterthe gutter 11,'end the adjusted hair held fast between the gutters untilthe heating procedure now following has been finished. 25

I Wishit to be understood that I do not limit myself'to the exactdrteilsof tongs shown merel by we of examples. Various departures 'rom thesedetails are possible Without, departing from the gist and scope of theinvention.

I claim 1'. Hair undulating tongs, comprising, in combination with thegrips and the of the tong body members, a gutterdike undulating memberattached to one of said body members; another gutter-like undulatingmember attached to the other body member and adapted to be placed intothe first-mentioned undulating member and having a longitudinal slot inits bottom; a ledge located in said slot and restingnpon the bottom ofthe first-mentioned undulating member;

m In

combination with the grips and the legs of the tong'body members, agutter-like undulatin member attached to one of said body mem ers;another gutter-like undulating member attached to the other body memberand adapted to be placed into the first-mom tioned undulating member andhaving a. longitudinal slot in its bottom; a ledge located in said slotand resting upon the bottom of the first-mentioned undulating member;

transverse ells in the second undulating member; a shaft extendingthrough this member and located in said walls; a cam affixedto saidshaft and bearing on saidledge; means for turning said shaft withsiudcam;

a slide located over said-second undulating gutter; and spikesextending'from the edges l p v of said slide towards the otherundulating gutter, the 'saidsl aft with said slide and its spikes beinglongitudinally shiftable with respect to the saidtwo gutterdikeundulatlug-members, substantially and for the purpose set forth. 1
